VirtualRPC is an emulator of Acorn Computers' Risc PC computer.

Initially VirtualRPC was only available bundled with the MicroDigital Alpha range of PC laptops,[8][2] but was later made available as a standalone product for sale.[9] In 2003, the developers reached an agreement with RISCOS Ltd to license its OS.[10]

VirtualRPC comes in four versions, with support for emulating ARM7 or ARM7 and StrongARM[11] each coming with either RISC OS 4.02 or RISC OS Adjust 4.39.[6]

Hardware bundles[edit]

Initially VirtualRPC was included on the MicroDigital Alpha range of PC laptops, and it has also been shipped by Advantage Six on the A5 series[12] and by R-Comp in their RISCube/SpaceCube/RiscBook range.[13]
